Garbage secondary classification treatment device adopting microbial method and garbage treatment method

Abstract

The invention discloses a garbage secondary classification treatment device adopting a microbial method. The device comprises a treatment box, wherein a crushing drum, a reactor and a product classified purification device are respectively mounted in the treatment box sequentially from top to bottom through a grinding chamber, a microbial reaction chamber and an enzymatic hydrolystate treatment chamber; a heating device, a gas outlet pipe and a pH detection device are mounted on the side wall of the reactor; the product classified purification device comprises a separation box, a leachate treatment box and an odor biotreatment box, and a gas pipeline system is mounted on the odor biotreatment box. The method comprises the steps as follows: after primary tretament of the garbage, separatingproducts into three forms including gas, liquid and solid, and then, purifying sewage and odor. The purification efficiency is high, so that garbage is sterilized and disinfected repeatedly, harmfulsubstances of the garbage are more thoroughly cleared, and the device completely conforms to the environmental protection theme.

Description

technical field [0001] The invention relates to the field of garbage treatment devices, in particular to a microbial garbage secondary classification treatment device and a garbage treatment method. Background technique [0002] Municipal solid waste mainly refers to the solid waste generated by units and residents in the city in their daily life and life services. The output of domestic waste in my country is increasing at a rate of 8%-10% every year. With the rapid development of the economy and the improvement of living standards, the proportion of recyclable waste and organic waste in municipal solid waste is gradually increasing. During the process of garbage collection and transshipment, the organic matter in the garbage will rot and deteriorate, and even the excrement. If it is piled up randomly, pathogenic microorganisms will seep into the ground with the rainwater, pollute the groundwater source, and directly or indirectly endanger the environment of urban resident...

AI Technical Summary

Problems solved by technology

[0004] (1) Landfill technology: The disadvantages are difficult site selection, land occupation, high construction and maintenance costs, and the recycling rate of waste resources is almost zero, and the generated waste seepage seriously threatens the groundwater system

[0005] (2) Incineration technology: Incineration can convert carbohydrates in garbage into carbon dioxide and water, but the infrastructure investment and transshipment costs are relatively high. Form secondary pollution and air pollution, easily destroy the protective layer of the earth

[0006] The emerging technology of microbial treatment of garbage generally requires multiple steps and multiple equipment or treatment pools to sort and treat garbage, so the efficiency of garbage treatment is slow, the cost is high, time-consuming and laborious, and there is no systematic device or equipment to directly treat the garbage Therefore, there are defects in the microbial treatment of municipal solid waste, such as low efficiency, harmful gas overflow of microbially treated garbage, and garbage seepage flowing out of polluted land.
